Low levels of fecal coliform
A) According to the nebular theory, the Solar System formed from a huge gaseous nebula which at a certain point was perturbated. Atoms and molecules started colliding, forming planetesimals (a sort of big rocks). The planetesimals were attracted to each other by gravity, forming bigger warm almost spherical objects called protoplanets, which at the end cooled down forming planets.
Therefore the correct answer is "all of the above".
b) The planets closer to the Sun were (and still are) subject to higher temperatures, due to their close distance to the Sun. In these conditions, rocky materials undergo condensation, while iced gaseous materials undergo vaporization. In the outer parts of the Solar System temperatures are too low to allow these transformations.
The correct answer is again "all of the above".
Answer:
in the nucleus of the atom
Explanation:
a p 3 x
Yes
Explanation:
From the graph, we can deduce that the wavelength changes with the speed of the wave.
This is a simple linear graph. A linear graph has a steady gradient and it shows two variables that increases proportionately.
Using the graph, we can establish that as the wavelength of the wave increases the time taken for one wave to pass through increases.
The speed of a wave is given as:
V = fλ
f is the frequency of the wave i.e the number of waves that passes through a point per unit of time
λ is the wavelength of the wave
The vertical axis on the graph shows the time for 1 wave trip, this is the wave period, T
f = 
Therefore;
speed of the wave = 
This can be evaluated by solving slope of the graph and finding the inverse.
We can see that as the speed of the wave changes, the wavelength will change.

<h3><u>Answer;</u></h3>
- Make up tissues
- The simplest level of organization of life
<h3><u>Explanation;</u></h3>
- <em><u>Cells are the smallest part of an organism that can carry out all of life functions. They are the basic functional unit of all living organisms.</u></em>
- According to cell theory all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells
- <em><u>A group of cells make up tissues. Tissues are a group of cells that are specialized to carry out specific functions in plants and animal bodies. </u></em>
